1 '0 on whom it may concern:

Be it known that 1, James E. REDMOND, a citizen of the United States,residing at Crandall, in the county of Murray and State of Georgia, haveinvented certain new and useful Improvements in Excavating Apparatus, ofwhich the following is a specification.

This invention relates to apparatus for excavating ditches alongsiderailway tracks, and its object is to provide an apparatus of this kindwhich can be easily and rapidly operated, and readily shifted to a newposition.

\Vith this object in view, the invention consistsin a novel combinationand arrangement of parts to be hereinafter described and'clailned,reference being bad to the accompanying drawings, in which- Figure 1 isa plan View showing the application of the invention. Fig. 2 is atransverse section on the line 2--'2 of 'Fig. 1. Fig. 3 is a plan viewshowing the parts in another position.

Referring specifically to the drawings, 10 denotes a ditch runningalongside a railway track 11. From the ditch rises an embankment 12. Ascraper 13 is employed for excavating the ditch, said scraper beingoperated by cables 1-1 and 15 extending forward and rearward therefromand leading to winding drums 16 and 17 mounted on a truck 18 located atthe top of the embankment. To the front end of the scraper is pivotallyconnected a bail 19 to which the cable 11 is removably attached. Thecable 15 is removably attached to the back of the scraper. The cable 1 1is wound on the drum 16 and the cable 15 on the drum 17.

The drums 1(3 and 17 are operated by a tract-ion engine 20, a suitabledrive-gear being provided. The tract-ion engine is also employed forhauling the truck 18 along the embankment.

In order to guide the cables 14 and 15 to their winding drums, thefollowing devices are provided: Some distance ahead of the truck 18 islocated a vertically positioned guide-pulley 21 around which the cable14 passes and thence extends obliquely down the en'ibankment to asnatch-block 29. At

the top of the embankment is mounted a horizontal. guide-roller 23 overwhich the cable also passes. The cable passes around the sheave of thesnatch-block and then extends rearward and is connected to the bail 19ot' the scraper 13. The snatch-block is anchored to one of the rails ofthe track by means of a shoe 24 which extends beneath the base of therail and has one of its ends hook-shaped, as indicated at 25 to engageone of the base flanges of the rail. The other end of the shoe has aneye to which is connected a chain 26 to which latter the snatch-block isconnected. Similar guide devices as herein described are provided forthe cable 15.

A scraper rigged up as herein described can be easily and rapidlyoperated to make a ditcl'r alongside the track. ()ne of the drums pullsthe scraper forward and the other drum rearward for a new load. Theapparatus can be readily taken up and :moved 't'ori 'ard for a new cut,as the snatchblocks permit the cables to be taken outof the same withoutreeving them there through.

A, third snatch-block 27 is anchored to the track rail a short distanceto the rear of the first described snatch-block 22. This snatchblock Idirectly in line with the pulley 21 and is employed for guiding thescraper 13 up to the top of the embankment 12, which done bydisconnecting the cable 14 from the forward snatch block 22 when thescraper reaches the snatch-block 27, and connecting the cable 15 to thesnatch-block 27. The cable 14: being now hauled in will pull the scraperup to the top of the embankment. Fig. 3 shows the parts arranged for thelast described operation.

The scraper can be detached and a plow used in its place.

To each end of the truck 18 is adjustably connected by means of a seriesof holes 28 a guide pulley 2.), the same being designed for use in casethe scraper is to be dumped out of line of the guide pulleys 21.

I claim:

1. In an ex *avating apparatus, a. scraper, operating cables connectedto the front and the rear of the scraper, winding drums on which thecables are wound, guide pulleys for the cables located in front of thewinding drums, a guide pulley behind the scraper from which pulley therear cable passes to the scraper, a pair of guide pulleys in front ofthe scraper over one of which pulleys the front cable passes to thescraper, said front cable being disengageable from the last mentionedpulley, and the rear cable being disengageable from the rear pulley andengageable with the other one of the front pulleys when the scraper isadjacent to said operating cables connected to the front and to the rearof the scraper, winding drums on which the cables are Wound, a guidepulley behind the scraper over which the rear cable passes,a pair ofguide 'pulleysin front of the scraper over one of which pulleys thefront cable passes, said front cable being disengageable from the lastmentioned pulley, and the rear cable being disengageable from the rearpulley and engageable with the other one of the front pulleys when thescraper is adjacent to said front pulley.

In testimony whereof I aflix my signature in presence of two witnesses.
